Paul Ekman is the actual founder for the Science of Emotions and most of his research and science is what has helped create the show, which is what the show is based on. Cal Lightman (played by Tim Roth as the head researcher of the Lightman Group) is a reflective version of Paul Ekman (that's just my opinion). Ekman helps direct the science within the show such as micro expressions, micro gestures, body language, and, his specialty, emotions. I love the marketing gimmick behind all of this, but I guess I can contribute to it since I am just as fascinated by Behavioral Science (Anthropology) myself. But there is a massive amount of psychology behind it all as well.

The show is amazing (in my opinion) since it is original and has a premise in Anthropological Forensics. The Drama aspect of it is just as intriguing as the science with subtle hints to straight forward statements, and subtle actions to drastic manipulations, all to find out the truth in, both, the real, and characters personal, worlds. It gives you a chance to connect with each character by learning to recognize how they feel from their own perspectives with secrets and twists that can only be picked up on by knowing and applying the science that builds the show which only leaves you on the edge of your seat in anticipation of Dr. Lightman's (Tim Roth) next unpredictable (or, if you're good enough, predictable) move. With a unique cast and brand new, cutting edge, science and moderate to well liked actors, and guest stars... I'd say this show just leaves you wanting more.

A Fair WARNING to any viewer: once you learn the science... it's hard to not use it and even harder to properly use it. I would know, I've been trying to learn this stuff for the past 5 years and it's a double edged sword. Even though the Emotions aspect of it is useful... but it's still the same case. The show gives enough basic information (as long as you keep up with it) to keep up with Lightman Group showing new things with real world, and scarcely current, examples. In each episode they show a new gesture, emblem, and facial expression from extreme (open / not concealed) to subtle (concealed / micro) expressions and explain the science.
